Slack integration Slack is an instant messaging platform especially appreciated by the software developer community. With Pandora FMS you will be able to get alert messages by simply adding a channel and an application to the account previously created in Slack.

You should start by accessing the page dedicated to the Slack API, identify yourself and use the "Create a custom app" option. Select “From scratch” Assign a name and select a workspace for the application and click on "Creat e app" . Now you must go to the configuration of the newly created application and set the scope.

Define the channel through which the application messages will be sent. Select the desired channel and click Allow . When you install the application, a User OAuth Token is generated, so copy this value. The next step is the application permission settings in Slack. Slack configuration: permissions and credentials In the Basic Information option you will be able to access the application credentials ( App Credentials ), which you should never share, in any case. In the same way, access to OAuth & Permissions to copy the authorization token that you will place in Pandora FMS.
